fix: Project knowledge graph for structural defect detection (#629)

Browse source 
Add lib/build-graph.py that builds a NetworkX DiGraph from project docs
and forge API, runs structural analyses (orphans, cycles, disconnected
clusters, thin objectives, bottlenecks), and outputs a JSON report.

Predictor and reviewer agents now call build-graph.py before launching
their Claude sessions and inject the report as context.
